UCSC import: what should my file look like?
~2020 lines, with the following header line:
bin name chrom strand txStart txEnd cdsStart cdsEnd exonCount exonStarts exonEnds score name2 cdsStartStat cdsEndStat exonFrames
txStart: Transcript start site
cdsStart: CodingSequence start site
Note: UCSC is updated frequently, you might get a slightly different number of lines. If you only get one row in this file, make sure you requested the entire chr22, not just one position.
